How Brain Organoids Work (And Why They Could Replace Silicon)

Can Medicine Keep Up with AI? — Dr. Yeshe Kway (Oxford)

Somewhere in Oxford, there’s an AI that can produce a contrast-enhanced cardiac MRI without ever injecting the contrast. No needle, no gadolinium, no risk. It works — and it has for years. Walk into a community hospital in Dallas tomorrow, and you still can’t get it. In this episode, Dr. Harvey Castro hosts — with co-hosts Ed Marx and Dr. Isha Mannering — a conversation with Dr. Yeshe Kway, a medical data scientist in Oxford’s Zhang Group building the AI that reads cardiovascular MRI. Together they take on the question every health-system leader is quietly asking: can medicine actually keep up with AI? They range across what AI can now see inside the whole body, why reactive medicine is giving way to proactive care, the unglamorous economics that strand breakthrough imaging one mile short of the patient, the ethics of telling a healthy child they may get sick someday, whether an employer could one day use AI against you, and a blunt warning about AI “poisoning” the well of medical knowledge. WHAT YOU WILL DISCOVER: * Cold open — can medicine keep up? * Meet the panel + Yeshe’s path: Germany → Singapore → Oxford * What can AI actually see inside your whole body? * Reactive medicine is dying — what replaces it? * It works — so why can’t your hospital use it? (the adoption wall) * Should we tell a child they’ll get sick? (pediatric early-risk ethics) * Predicting disease from a routine eye scan — and who could use it * Is the doctor who won’t use AI already behind? * Is AI poisoning medical knowledge? * Closing: human + AI REFERENCED IN THE SHOW: 🖇️ Dr. Harvey Castro’s work on ChatGPT in healthcare — https://www.harveycastromd.com/ [https://www.harveycastromd.com/] CONNECT WITH US: Dr. Harvey Castro, ER Physician, #DrGPT™ 💼 LinkedIn — https://www.linkedin.com/in/harveycastromd/ [https://www.linkedin.com/in/harveycastromd/] 🔗 Website — https://www.harveycastromd.com/ [https://www.harveycastromd.com/] 📷 Instagram — https://www.instagram.com/harveycastromd/ [https://www.instagram.com/harveycastromd/] 📑 Substack — https://harveycastromd.substack.com/ [https://harveycastromd.substack.com/] Edward Marx, CEO, Advisor 💼 LinkedIn — https://www.linkedin.com/in/edwardmarx/ [https://www.linkedin.com/in/edwardmarx/] 🔗 Website — https://www.marxadvisory.com [https://www.marxadvisory.com]/ 📹 YouTube — https://www.youtube.com/@EdwardMarx [https://www.youtube.com/@EdwardMarx] Dr. Isha Mannering — Board-Certified Pediatrician, Founder of InTuneMD LinkedIn — https://linkedin.com/in/drisha [https://linkedin.com/in/drisha] Special Guest: Dr. Yeshe Kway, Medical Data Scientist, Zhang Group (AI in Cardiovascular Imaging), University of Oxford 💼 LinkedIn — https://www.linkedin.com/in/yeshe-kway-b77b53185/ [https://www.linkedin.com/in/yeshe-kway-b77b53185/] Visit our website: https://signalandsymptoms.com/ [https://signalandsymptoms.com/] Get advisory insights about Healthcare AI — at zero cost: https://junaidkaliamd.substack.com/ [https://junaidkaliamd.substack.com/] Medical disclaimer: This conversation is for general informational purposes and is not medical advice.

AI Won’t Replace Your Pediatrician — But It Will Change the Visit

The hardest part of a pediatric visit now happens before the appointment even begins. In this episode, Dr. Isha Mannering — a board-certified pediatrician with 16 years in the Dallas–Fort Worth area and founder of InTuneMD — joins Dr. Junaid Kalia, Dr. Harvey Castro, and Ed Marx to confront a new reality in the exam room: parents arrive having already consulted TikTok and ChatGPT, and the physician’s first job is winning back trust. Drawing on more than a decade in practice and her decision to go independent, Isha makes the case for treating AI as a tool, not a takeover — one that can hand clinicians back their time, sharpen early-warning “signals” in young patients, and bring care into the home. The conversation widens into pediatric AI in practice, the rural-versus-frontier care divide, at-home sick care, and a blunt warning to health systems: enable entrepreneurship within your walls, or be disintermediated by those who will. WHAT YOU WILL DISCOVER: * Cold open + welcome (Junaid, Harvey, Ed + Dr. Mannering) * Why trust is eroding: the viral-TikTok rare-disease scare * AI as a tool: the “healthcare influencer” + scribe & signal * Going independent: “figuring it out as I go” * Authenticity: earning the trust of parents AND kids * “Put the laptop down”: reclaiming the visit * Pediatric AI in practice: comic discharge notes + an NFC plushie * Catching the signal early: “never trust a newborn” * At-home sick care: the 2 a.m. fever * The hospital reckoning: adapt or be disintermediated * Closing: human + AI — have fun with it REFERENCED IN THE SHOW: 🖇️ Dr. Harvey Castro’s work on ChatGPT in healthcare — https://www.harveycastromd.com/ [https://www.harveycastromd.com/] CONNECT WITH US: Dr. Junaid Kalia, Neurocritical Care Specialist and Founder of SaveLife.AI™ 💼 LinkedIn — https://www.linkedin.com/in/junaidkaliamd [https://www.linkedin.com/in/junaidkaliamd] 🔗 Website — https://www.junaidkalia.com/ [https://www.junaidkalia.com/] 📹 YouTube — https://www.youtube.com/@junaidkaliamd [https://www.youtube.com/@junaidkaliamd] Dr. Harvey Castro, ER Physician, #DrGPT™ 💼 LinkedIn — https://www.linkedin.com/in/harveycastromd/ [https://www.linkedin.com/in/harveycastromd/] 🔗 Website — https://www.harveycastromd.com/ [https://www.harveycastromd.com/] 📷 Instagram — https://www.instagram.com/harveycastromd/ [https://www.instagram.com/harveycastromd/] 📑 Substack — https://harveycastromd.substack.com/ [https://harveycastromd.substack.com/] Edward Marx, CEO, Advisor 💼 LinkedIn — https://www.linkedin.com/in/edwardmarx/ [https://www.linkedin.com/in/edwardmarx/] 🔗 Website — https://www.marxadvisory.com [https://www.marxadvisory.com]/ 📹 YouTube — https://www.youtube.com/@EdwardMarx [https://www.youtube.com/@EdwardMarx] Special Guest: Dr. Isha Mannering, Board-Certified Pediatrician, Founder of InTuneMD 💼 LinkedIn — https://linkedin.com/in/drisha [https://linkedin.com/in/drisha] Visit our website: https://signalandsymptoms.com/ Get advisory insights about Healthcare AI — at zero cost: https://junaidkaliamd.substack.com/ [https://junaidkaliamd.substack.com/] Medical disclaimer: This conversation is for general informational purposes and is not medical advice.

How Brain Organoids Work (And Why They Could Replace Silicon)

The foundation of tomorrow's diagnostics is being rebuilt — and it starts in biology, not silicon. In this episode, Edmund White, biomedical innovator and bestselling author, joins the conversation to challenge an assumption quietly embedded in every AI tool entering healthcare: that silicon is the only material worth building on. Drawing from three decades at the intersection of cardiac care and medical innovation, Edmund traces a through-line from digital twins of children's hearts to brain organoids — arguing that biology's energy efficiency and adaptability aren't limitations to engineer around, they're the very properties that could unlock earlier intervention and more precise patient outcomes. The conversation widens from there into the economics of AI adoption, the coming bubble, and what it will take for healthcare systems and policymakers to get ahead of a shift that's already in motion.

Why AI Isn't the Tech Hype Hospital Leaders Think It Is

We built a healthcare system engineered for sick care, but the future of medicine belongs to those who seek health. In this episode, global Digital Health Futurist Philippe Gerwill joins the panel to unpack the real bottlenecks stalling clinical innovation. He highlights a critical inversion happening in modern medicine. Historically, technology lagged behind clinical needs. Today, advanced technology vastly outpaces our institutional capacity to adopt it. The conversation delivers an evidence-based perspective on how to manage this rapid acceleration from a global innovator who understands both big pharma infrastructure and the reality of clinical adoption. Tune in to discover how forward-thinking medical leaders are realigning systemic incentives to transition from algorithmic task managers back to true, humanist healers.

Healthcare AI: What To Know, What's Still Broken, and Where To Go Next

What does it actually cost when a diagnosis comes six months too late, a test gets ordered twice, or a treatment decision gets made without the best information available? In this special recap episode of Signal & Symptoms, we synthesize the strongest healthcare AI insights from previous episodes — moving from the promise of what AI can do, to the real patient stories that reveal what's at stake when we delay, to an honest look at the barriers still standing in the way, and finally to the path ahead for clinicians and leaders ready to act. This isn't a hype episode. It's a practical reckoning: AI is already changing how diagnoses get made, how patients advocate for themselves, and how the next generation of healthcare standards will be written. The only question is whether you'll help shape it — or watch it happen without you.
